Tube valves

Hello everyone,

I have AVON searider 5.4 and unfortunately 4 of all tubes loose air.
I would like to ask you if its possible to replace old valves to new one without making extra hole in tubes.

Thanks for your help,
zubol

Are you sure you're losing air through the valves?

Inflate the tubes, then spray them down with soapy water - the leaks should become quite apparent (large mass of small bubbles.)

Thanks for your response.

Unfortunately I made this test a few times and I could not find any bubbles.
So I've deducted valves. When I sprayed water into the valves I saw bubbles.

I fitted complete new valves to Aging Youths Humber for him a couple of years ago, as they were buggered.

They arrived with a circular patch of Hypalon already attached, so I just cut tightly around the old valve with a craft knife and stuck the new valve/patch over the hole.
It was a bit fiddly as the tube was obviously deflated, but it wasn't too bad.

This may not be the proper way to do it, but they held air perfectly at least up until he sold it a couple of months ago.

You can also just replace the inserts if you are careful. Do a search for Ribshops post about doing it with a piece of cotton as a safety line.
I did the valves this way on my boat following his method and it worked fine, but my valves were not that bad and did only need the inserts changed.

It would be worth trying to replace just the inserts if you can identify the type required.

They are surprisingly cheap and can make the valve like new.

This thread may help
Leafield C7 inflation valves

Thanks all of you. There is a still huge chance to do this without "surgery"

Do you know what kind of valves my RIB has? It is AVON searider 5.4
I am a new in RIBs, this is my first boat and I do not want to brake something.

Cheers.

I have just last night changed the insides of a couple of A& valvves - first tiem I have ever done any valve type work & it was very simple stuff . A little bit of car eneeded not to drop the bits inside the tubes, but they are like new now.

As was said have alook at what you have, get the right bits & give it a go !
